42 PCB007 MAGAZINE I MAY 2020 • Augmented reality will eventually take the place of new equipment install and training Conclusion When we come out the other side—and we will, at some point—there should be some long-term benefits for all persons including cleaner air, less traffic, stabilized greenhouse gases, better medical care, lower gas prices, and more. PCB007 Paul Benke is the CEO of Zero Defects International. Michaela Brody is the president of Zero Defects International. • Meetings are "virtual" using Zoom or other equivalent software • Drones are being used for pharmaceutical deliveries and other applications If we carry this forward to the industry in which we operate—PCB fabrication and as- sembly—just think of the possibilities: • Onboarding and new customer startup can be done by Team Viewer and Zoom • Periodic quality meetings can be conducted to ensure that specifications are up to date and dynamic, including root cause analysis and corrective action • Rules regarding "export" will be revisited • Management will be able to scale quickly for new customers if more manufacturing returns to the U.S. • Offshore service providers can be trained remotely without the need for visas and extended travel—in harmony with today's travel and cost limitations • Drones can deliver quick turn boards or essential component, and supply chain costs will be streamlined femtosecond) with optics and a specialized type of cam- era. The optics break up individual femtosecond pulses of laser light into a train of even shorter pulses, with each of those pulses capable of producing an image in the camera. Wang says the technology could open up new avenues of research in fields that include fundamental physics, next-generation semiconductor miniaturization, and the life sciences.

(Source: Caltech) The new camera developed in the lab of Lihong Wang, Bren Professor of Medical Engineering and Electrical En- gineering in the Andrew and Peggy Cherng Department of Medical Engineering at Caltech, is capable of taking as many as 70 trillion frames per second. That is fast enough to see waves of light traveling and the fluorescent decay of molecules. The camera technology, which Wang calls compressed ultrafast spectral photography (CUSP), is similar in some respects to previous fast cameras he has built, such as his phase-sensitive compressed ultrafast photography (pCUP) device, which can take one tril- lion frames per second of trans- parent objects and phenomena. CUSP combines a laser that emits extremely short pulses of laser light that last only one quadrillionth of a second (one New Ultrafast Camera Takes 70 Trillion Pictures Per Second
